THE FIELD OF THE INVENTION

The present invention is in the field of soybean variety S06-MT9206166 breeding and development. The present invention particularly relates to the soybean variety S06-MT9206166 and its progeny, and methods of making.

BACKGROUND OF THE INVENTION

Soybean Glycine max (L) is an important oil seed crop and a valuable field crop. However, it began as a wild plant. This plant and a number of other plants have been developed into valuable agricultural crops through years of breeding and development. The pace of the development of soybeans, into an animal foodstuff and as an oil seed has dramatically increased in the last one hundred years. Planned programs of soybean breeding have increased the growth, yield and environmental hardiness of the soybean germplasm.

Due to the sexual reproduction traits of the soybean, the plant is basically self-pollinating. A self-pollinating plant permits pollen from one flower to be transferred to the same or another flower of the same plant. Cross-pollination occurs when the flower is pollinated with pollen from a different plant; however, soybean cross-pollination is a rare occurrence in nature.

Thus the growth and development of new soybean germplasm requires intervention by the breeder into the pollination of the soybean. The breeders' methods of intervening in the pollination depend on the type of trait that is being bred. Soybeans are developed for a number of different types of traits morphological (form and structure), phenotypical, or for traits like growth, day length, temperature requirements, initiation date of floral or reproductive development, fatty acid contents, insect resistance, herbicide resistance and yield. The genetic complexity of the trait often drives the selection of the breeding method.

Due to the number of genes within each chromosome, millions of genetic combinations exist in the breeders' experimental soybean material. This genetic diversity is so vast that a breeder cannot produce the same two cultivars twice using the exact same starting parental material. Thus, developing a single variety of useful commercial soybean germplasm is highly unpredictable, and requires intensive research and development.

The development of new soybeans comes through breeding techniques, such as: recurrent selection, mass selections, backcrossing, single seed descent and multiple seed procedure. Additionally, markers' assisted breeding allows more accurate movement of desired alleles or even specific genes or sections of chromosomes to be moved within the germplasm that the breeder is developing. RFLP, RAPD, AFLP, SSR, SNP, SCAR, isozymes, are all forms of markers that can be employed in breeding soybeans or in moving traits into soybean germplasm. Other breeding methods are known and are described in various soybean textbooks.

When a soybean variety is being employed to develop a new soybean variety or an improved variety the selection methods include backcrossing, pedigree breeding, recurrent selection, modified selection and mass selection. The efficiency of the breeding procedure along with the goal of the breeding is the factors for determining which selection techniques are employed. A breeder continuous evaluates the success of the breeding program and therefore the efficiency of any breeding procedure. The success is usually measured by yield increase, commercial appeal and environmental adaptability of the developed germplasm.

The development of new soybean cultivars most often requires the development of hybrid crosses (some exceptions being initial development of mutants directly through the use of the mutating agent, certain materials introgressed by markers, or transformants made directly through transformation methods) and the selection of progeny therefrom. Hybrids can be achieved by manual manipulation of the sexual organs of the soybean or by the use of male sterility systems. Breeders often try to identify true hybrids by a readily identifiable trait or the visual differences between Inbred and hybrid material. These heterozygous hybrids are then selected and repeatedly selfed and reselected to form new homozygous soybean lines.

Mass and recurrent selection can be used to improve populations. Several parents are intercrossed and plants are selected based on selected characteristics like superiority or excellent progeny. Outcrossing to a number of different parents creates fairly heterozygous breeding populations.

Pedigree breeding is commonly used with two parents that possess favorable, complementary traits. The parents are crossed to form a F1 hybrid. The progeny of the F1 hybrid is selected and the best individual F2s are selected; this selection process is repeated in the F3 and F4 generations. The inbreeding is carried forward and at F5-F7 the best lines are selected and tested in the development stage for potential usefulness in a selected geographic area.

In backcross breeding a genetic allele or loci is transferred into a desirable homozygous recurrent parent. The trait is in the donor parent and is tracked into the recurrent parent. The resultant plant is like the recurrent parent with the new desired allele or loci.

The single-seed descent method involves use of a segregating plant population for harvest of one seed per plant. Each seed sample is planted and the next generation is formed. When the F2 lines are advanced to F6 each plant will be derived from a different F2. The population will decline due to failure of some seeds, so not all F2 plants will be represented in the progeny.

New varieties must be tested thoroughly to compare their development with commercially available soybeans. This testing usually requires at least two years and up to six years of comparisons with other commercial soybeans. Varieties that lack the entire desirable package of traits can be used as parents in new populations for further selection or are simply discarded. The breeding and associated testing process is 8 to 12 years' of work prior to development of a new variety. Thousands of varietal lines are produced but only a few lines are selected in each step of the process. Thus the breeding system is like a funnel with numerous lines and selections in the first few years and fewer and fewer lines in the middle years until one line is selected for the final development testing.

The selected line or variety will be evaluated for its growth, development and yield. These traits of a soybean are a result of the variety's genetic potential interacting with its environment. All varieties have a maximum yield potential that is predetermined by its genetics. This hypothetical potential for yield is only obtained when the environmental conditions are perfect. Since prefect growth conditions do not exist, field experimentation is necessary to provide the environmental influence and to measure its effect on the development and yield of the soybean. The breeder attempts to select for good soybean yield potential under a number of different environmental conditions.

Selecting for good soybean yield potential in different environmental conditions is a process that requires planning based on the analysis of data in a number of seasons. Identification of the varieties carrying a superior combination of traits, which will give consistent yield potential, is a complex science. The desirable genotypic traits in the variety can often be masked by other plant traits, unusual weather patterns, diseases, and insect damage. One widely employed method of identifying a superior plant with such genotypic traits is to observe its performance relative to commercial and experimental plants in replicated studies. These types of studies give more certainty to the genetic potential and usefulness of the plant across a number of environments.

In summary, the goal of the soybean plant breeder is to produce new and unique soybeans and progeny of the soybeans for farmers' commercial crop production. To accomplish this the plant breeder painstakingly crosses two or more varieties or germplasm. Then the results of this cross are repeatedly selfed or backcrossed to produce new genetic patterns. Newer avenues for producing new and unique genetic alleles into soybeans include introducing mutations or transgenes into the genetic material of the soybean are now in practice in the breeding industry. These genetic alleles can alter pest resistance such as insect resistance, nematode resistance, herbicide resistance, or they can alter the plant's disease tolerance, or its fatty acid compositions, the amount of oil produced, and/or the amino acid compositions of the soybean plant or its seed.

The traits a breeder selects for when developing new soybeans are driven by the ultimate goal of the end user of the product. Thus if the goal of the end user is to resist a certain plant disease so overall more yield is achieved, then the breeder drives the introduction of genetic alleles and their selection based on disease resistant levels shown by the plant. On the other hand, if the goal is to produce a specific oil, with a high level of oleic acid and a lower level of linoleic acid, then the breeder may drive the selection of genetic alleles based on levels of fatty acids in the seed and accept some lesser yield potentials or other less desirable agronomic traits.

The new genetic alleles being introduced in to soybeans are widening the potential uses and markets for the various products and by-products of the oil from the seed plants such as soybean. A major product extracted from soybeans is the oil in the seed. Soybean oil is employed in a number of retail products such as cooking oil, baked goods, margarines and the like. Another useful product is soybean meal, which is a component of many foods and animal feedstuffs.

Definitions of Staging of Development

The plant development staging system employed in the testing of this invention divides stages as vegetative (V) and reproductive (R). This system accurately identifies the stages of any soybean plant. However, all plants in a given field will not be in the stage at the same time. Therefore, each specific V or R stage is defined as existing when 50% or more of the plants in the field are in or beyond that stage.

The first two stages of V are designated a VE (emergence) and VC (cotyledon stage). Subdivisions of the V stages are then designated numerically as V1, V2, V3 through V (n). The last V stage is designated as V (n), where (n) represents the number for the last node stage of the specific variety. The (n) will vary with variety and environment. The eight subdivisions of the reproductive stages (R) states are also designated numerically. R1=beginning bloom; R2=full bloom; R3=beginning pod; R4=full pod; R5=beginning seed; R6=full seed; R7=beginning maturity; R8=full maturity.

BROWN STEM ROT (BSR)—This disease is caused by the fungus Phialophora gregata. The disease is a late-season, cool-temperature, soilborne fungus which in appropriate favorable weather can cause up to 30 percent yield losses in soybean fields. For purposes of these tests the information is gathered in a greenhouse with a plant in a pot then a root dip procedure is employed.

SUDDEN DEATH SYNDROME (SDS or SDS_R)—This disease is caused by slow-growing strains of Fursarium solani that produce bluish pigments in culture. The disease is a mid to late season, soil borne disease that occurs in soybean fields with high yield potential. Yield losses may be total or severe in infected fields. Sudden Death Syndrome (SDS) is based on leaf area affected. The scale used for these tests is 1-5 or if identified as SDS_R the scale is 1-9.

SOYBEAN CYST NEMATODE—The Soybean Cyst Nematode (SCN) Heterodera glycines, is a small plant-parasitic roundworm that attacks the roots of soybeans. Soybean Cyst Nematode (SCN) for purposes of these tests is done as a greenhouse screen—30 day screen using infested soil. The rating scale is based upon female reproduction index on a susceptible check set where <10%=R (RESISTANT); <30%=MR (MODERATELY RESISTANT); <60%=MS (MODERATELY SUSPECTIBLE); >60%=S (SUSPECTIBLE). In priority order, the screening races include: 3, 14, & 1.

MATURITY DATE. Plants are considered mature when 95% of the pods have reached their mature color. The number of days is either calculated from August 31 or from the planting date. (MR#) wherein # equals days.

RELATIVE MATURITY GROUP (RM). Industry Standard for varieties groups, based day length or latitude. Long day length (northern areas in the Northern Hemisphere) is classified as (Groups 000, 00, 0). Mid day lengths variety groups lie in the middle (Groups I-VI). Very short day lengths variety groups (southern areas in Northern Hemisphere) are classified as (Groups VII, VIII, IX).

SEED YIELD (Bushels/Acre). The yield in bushels/acre is the actual yield of the grain at harvest.

SHATTERING. The rate of pod dehiscence prior to harvest. Pod dehiscence involves beans dropping out of the pods. Shatter (SHAT) for these tests the rating of pre-harvest loses is based on amount of plants with open pods.

PLANT. Means the plant, the plant's cells, plant protoplasts, plant cells of tissue culture from which soybean plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of the plants, such as pollen, nodes, roots, flowers, seeds, pods, leaves, stems, pod and the like.

The present invention is S06-MT9206166. This soybean is developed for use of the beans. S06-MT9206166 is to be sold commercially in the upper Midwest where other early to mid Maturity Group 1 soybeans are grown.

This soybean variety in one embodiment carries one or more transgenes, for example, the glyphosate tolerance transgene, a desaturase gene or other transgenes. In another embodiment of the invention does not carry any herbicide resistance traits. In yet another embodiment of the invention, the soybean does not carry any transgenes but carries alleles for aphid resistance, cyst nematode resistance and/or brown stem or the like.

The traits of the invention are listed below.

The instant invention provides methods and composition relating to plants, seeds and derivatives of the soybean cultivar S06-MT9206166. Soybean cultivar S06-MT9206166 has superior characteristics. The S06-MT9206166 line has been selfed sufficient number of generations to provide a stable and uniform plant variety.

Cultivar S06-MT9206166 shows no variants other than expected due to environment or that normally would occur for almost any characteristic during the course of repeated sexual reproduction. Some of the criteria often used to select in various generations include: seed yield, emergence, appearance, disease tolerance, maturity, plant height, and shattering data.

The inventor believes that S06-MT9206166 is similar to the comparison varieties shown in the last table. However, as shown in the table, S06-MT9206166 differs from these cultivars.

Direct comparisons were made between S06-MT9206166 and the listed commercial varieties. Traits measured included yield, maturity, moisture, lodging, plant height, branching, field emergence, and shattering. The results of the comparison are presented in below. The number of tests in which the varieties were compared is shown.

The present invention S06-MT9206166 can carry genetic engineered recombinant genetic material to give improved traits or qualities to the soybean. For example, but not limitation, the present invention can carry, the glyphosate resistance gene for herbicide resistance as taught in the Monsanto patents (WO92/00377, WO92/04449, U.S. Pat. No. 5,188,642 and U.S. Pat. No. 5,312,910) or STS mutation for herbicide resistance. Additional traits carried in transgenes or mutation can be transferred into the present invention. Some of these genes include genes that give disease resistance to sclerotina such as the oxalate oxidase (Ox Ox) gene as taught in PCT/FR92/00195 Rhone Polunc and/or an oxalate decarboxylase gene for disease resistance or genes designed to alter the soybean oil within the seed such as desaturase, thioesterase genes (shown in EP0472722, U.S. Pat. No. 5,344,771) or genes designed to alter the soybean's amino acid characteristics. This line can be crossed with another soybean line that carries a gene that acts to provide herbicide resistance or alter the saturated and/or unsaturated fatty acid content of the oil within the seed, or the amino acid profile of the seed.

The present invention S06-MT9131105 is employed in a number of plot repetitions to establish trait characteristics. The present invention is grown in a number of regions for testing and researching the invention in various environmental interactions.

Geographic Summary

The target variety yield is given as a percent of the trial average at all locations shown in FIG. 1 and each geographic segment West to East or Central (Cntrl) to South East where there are three or more locations. The plots for these trials are 17.5 plots with 30-inch rows. The plants in the plots are a combination of experimental material and commercial material. There are usually 36 varieties and there are approximately 300 plants of each variety with two replications in about 20-25 locations. The data in FIG. 1 is only charted if there are at least 3 or more locations. N>=3

The present invention differs from the mean of the comparison commercial soybean lines in that it is not meeting the mean of the group of soybeans (GRP_MN) that were tested and displayed in this geographic segment chart (GSEGC). When all of the regions that the testing data for the present invention are included the present invention is about 107.03% of the group mean. However, this invention works very well in the Central region where it is 108.28% of the Group Mean. The present invention is well adapted in the West region also 106.52%.

The present invention S06-MT9206166 (identified herein as MT9206166) is employed in a trial for testing a number of yielding environments. The results of the grain yield at standard moisture are shown in the chart as shown in FIG. 2. The present invention is a variety that will yield above the mean of most soybeans in a low yielding environment.

Each of these lines has their own positive traits. Each of these lines is different from the present invention. The present invention has higher yield at standard moisture than do the other comparison lines. The present invention shows less harvest lodging then all of the comparisons except for two. The ID-R rating is one of the highest numbers (1=best) when compared with the comparison commercial lines. Thus, indicating very high IDC sensitivity. The yield and other data is a snapshot of each of these lines' results in the specific environment and will differ when other environmental interactions are measured.

This invention also is directed to methods for producing a new soybean plant by crossing a first parent plant with a second parent plant wherein the first or second parent plant is the present invention. Additionally, the present invention maybe used in the variety development process to derive progeny in a breeding population or crossing. Further, both first and second parent plants can come from the soybean line S06-MT9206166. A variety of breeding methods can be selected depending on the mode of reproduction, the trait, and the condition of the germplasm. Thus, any such methods using the S06-MT9206166 are part of this invention: selfing, backcrosses, recurrent selection, mass selection and the like.

The scope of the present invention includes any use on S06-MT9206166 of marker methods. Through the use of markers such as SSRs, RFLP's, SNPs, Ests, AFLPs, gene primers, and the like to identify genetic alleles which can be identified and breed with marker assistance into the present invention with little to no superfluous germplasm being dragged into the present invention. This results in formation of the present invention plus for example, cyst nematode resistance, brown stem rot resistance, aphid resistance, phytothora resistance, IDC resistance, BT genes or male sterility genes or glyphosate tolerance genes or drought tolerance genes or alleles and the like. Transgenes maybe directly introduced into cultivar using genetic engineering and transformation techniques well known in the art, some of which are described above, or are originally introduced into a donor, parent using genetic engineering and transformation techniques, and using the donor in a marker assisted trait conversion process, the trait is moved for example by backcrossing. A transgene typically comprises a nucleotide sequence whose expression is responsible or contributes to the trait, under the control of a promoter capable of directing the expression of the nucleotide sequence at the desired time in the desired tissue or part of the plant. Constitutive, tissue-specific or inducible promoters all have different purposes and each could be employed. The transgene may also comprise other regulatory elements such as for example translation enhancers or termination signals. The transgene may be adapted to be transcribed and translated into a protein, or to encode RNA in a sense or antisense orientation such that it is not translated or only partially translated.

The scope of the present invention also includes any use on S06-MT9206166 of transformation methods. Transformation methods are means for integrating new genetic coding sequences (transgenes) into the plant's genome by the incorporation of these sequences into a plant through man's assistance. Many dicots including soybeans can easily be transformed with Agrobacterium. Methods of introducing desired recombinant DNA molecule into plant tissue include the direct infection or co-cultivation of plant cells with Agrobacterium tumefaciens, Horsch et al., Science, 227:1229 (1985). Descriptions of Agrobacterium vector systems and methods are shown in Gruber, et al., “Vectors for Plant Transformation, in Methods in Plant Molecular Biology & Biotechnology” in Glich et al., (Eds. pp. 89-119, CRC Press, 1993). Transformed plants obtained via protoplast transformation are also intended to be within the scope of this invention. The most common method of transformation after the use of agrobacterium is referred to as gunning or microprojectile bombardment. This process has small gold-coated particles coated with DNA (including the transgene) shot into the transformable material. Techniques for gunning DNA into cells, tissue, explants, meristems, callus, embryos, and the like are well known in the prior art. The DNA used for transformation of these plants clearly may be circular, linear, and double or single stranded. Usually, the DNA is in the form of a plasmid. The plasmid usually contains regulatory and/or targeting sequences which assists the expression of the gene in the plant. The methods of forming plasmids for transformation are known in the art. Plasmid components can include such items as: leader sequences, transit polypeptides, promoters, terminators, genes, introns, marker genes, etc. The structures of the gene orientations can be sense, antisense, partial antisense, or partial sense: multiple gene copies can be used.

After the transformation of the plant material is complete, the next step is identifying the cells or material, which has been transformed. In some cases, a screenable marker is employed such as the beta-glucuronidase gene of the uidA locus of E. coli. Then, the transformed cells expressing the colored protein are selected for either regeneration or further use. In many cases, a selectable marker identifies the transformed material. The putatively transformed material is exposed to a toxic agent at varying concentrations. The cells not transformed with the selectable marker, which provides resistance to this toxic agent, die. Cells or tissues containing the resistant selectable marker generally proliferate. It has been noted that although selectable markers protect the cells from some of the toxic affects of the herbicide or antibiotic, the cells may still be slightly affected by the toxic agent by having slower growth rates. If the transformed material was cell lines then these lines are regenerated into plants. The cells' lines are treated to induce tissue differentiation. Methods of regeneration of cellular are well known in the art. The plants from the transformation process or the plants resulting from a cross using a transformed line or the progeny of such plants are transgenic plants that carry the transgene.
